Check Intel's forum & other forums as well. Maybe even consider RMAing if necessary? From what I understand, the response Intel has given only covers a (possible) part of the problem & more or less amounts to "we don't necessarily know, & even if we did, we still don't", or something like that.
Some have complained about the cheap TIM used for the cpu. In the meantime, before you do anything else: feel the exhaust coming from your cooler, physically. Does it feel as hot as the temps indicate? Does it feel more like an old GPU that you could fry an egg on, or does it feel more like how a cpu's exhaust should? Maybe waiting on a bios or hardware monitoring update might be worth it (though I've alrdy seen reports from some of both stating updates were already done). It may also be Intel released a cpu that was hyped up to be awesome, and some of them are, but included those that are sub-par or poorly binned into the lottery, as well.
Intel announced to it's customers, who bought this kind of pricey, unlocked cpu from them & are having heat issues, to not overclock... Despite that unlocked CPUs have easy overclocking as a primary marketing point.
